How are melting glaciers controllers of the future environment?

Physics
1 answer:
KatRina [158]3 years ago
4 0

Answer:

Explanation: Today, the increasing temperature is causing ice caps on Mount Kilimanjaro and ice sheets in Antarctica and Greenland to melt (Lovgren 2004a) (see Appendix 2). This has resulted in the rise in sea level, causing many problems to the nature balance. Cold water fish cannot survive and even coral reefs are dying as the water is becoming too warm. This causes problems for people fishing them as a food source and influences the fisheries in general. Besides, Lovgren (2004b) said that the rising sea level can have serious impacts on low-lying countries, some of which like Indian Ocean’s Maldives or Nile Delta could be submerged. Not only will fishing be affected but people will also have difficulties in finding higher ground for living.

An imbalance in nature’s food chain would be caused by global warming. As ice sheets melt in the Antarctic, the polar bears would be adversely affected since the temperature is too warm for them to live. “Polar bears are entirely dependent on sea ice, you lose sea ice, you lose polar bears” (Malcolm 2004). Additionally, the seal and sea lion population that would otherwise be controlled by polar bears as part of their diet would multiply and overpopulation may occur, causing many fishes being eaten and depleted. This depletion affects fisheries and people living in the northern hemisphere because they must then find other food sources which would be difficult as their main source of protein and food are fish.

What did ancient astronomers think areas of the moon called mares might be?
Bumek [7]

The ancient astronomers think areas of the moon called mares might be Seas.

Option D  

<u>Explanation</u>:

The surface area of Earth's moon is dark, large, and is basaltic plains which are formed by ancient volcanic eruptions. They were dubbed as Maria, "ancient astronomers" who misunderstood them as actual seas. They are less reflective than highlands. Due to their iron-rich composition, they tend to appear dark from the naked eye. The Maria cover approximately about 16% of surface mostly on side that is visible from Earth. The few Maria on side that is too far are much smaller and residing mostly in very large craters. The ancient astronomers mistook the surface area as look like actual seas.

Question 2 - If Juan starts out at 10m/s, and in 15 s speeds up to 60 m/s, what is his acceleration?
34kurt

Answer:

B) 3.33 m/s²

Explanation:

Given that,

The initial velocity of Juan, u = 10 m/s

Final velocity of Juan,  v = 60 m/s

Time taken, t = 15 s

The acceleration is given by the relation

                          a = v-u/t  m/s²

Substituting in the above equation

                           a = 60 - 10 / 15

                           a = 3.33 m/s²

Hence, the acceleration of the Juan is, a = 3.33 m/s²
